PURPOSE
The risk of inferior vena cava (IVC) filter tilt during placement is significant and may limit filter retrieval. The purpose of the study was to determine if tilting of IVC filters on deployment is able to be reduced when using a femoral approach.
METHODS
Under fluoroscopic guidance, Cook Celect IVC filters that are not in axis with the IVC prior to full deployment were straightened in the long IVC axis using a stiff guidewire prior to release. This guidewire helps to center the apex of the filter in the IVC and allow proper deployment.
RESULTS
All 11 IVC filters deployed with this technique have been placed without tilt. No complications were encountered with this technique.
CONCLUSIONS
IVC filter tilt may lessen their efficacy and ability to be easily retrieved. By using this technique, we have virtually eliminated IVC filter tilt in our patients.
目的
下腔静脉（IVC）滤器在置入过程中发生倾斜的风险很大，可能会限制滤器的取出。本研究旨在确定在股静脉入路时使用该方法是否能减少 IVC 滤器在展开过程中的倾斜。
方法
在透视引导下，对在完全展开前与 IVC 不呈同轴的 Cook Celect IVC 滤器，在释放前使用硬导丝沿 IVC 长轴将其拉直。该导丝有助于将滤器的尖端中心置于 IVC 内，并允许正确展开。
结果
所有采用该技术展开的 11 个 IVC 滤器均未出现倾斜。该技术未出现任何并发症。
结论
IVC 滤器倾斜可能会降低其疗效和易取出性。通过使用该技术，我们几乎消除了患者 IVC 滤器倾斜的情况。
